Original application filed January 3, 1918, Serial No. 210,146. FatentNo. 1,292,399, dated January 19,

1919. Divided and this application filed January 17, 1919.

To all whom it may concern:

Be it known that I, F REDERIOK L. Mo- GAHAN, a citizen of the UnitedStates, residing at the city of Los Angeles, in the county Serial No.271,719.

5. As shown in Figure 2 and indicated in Flgure 1, this filter orpurifier 5 consists of three compartments constructed of any suitablematerial with walls 7 and partitions 8.

5 of Los Angeles and State of California, have @penings 9 and '10 permitthe fiow of water invented certain new and useful Imp-rovements inFilters, of which the following is a specification.

This application is a division from the application of the same inventorfor patent for locomotive filed January 3, 1918, Serial 210,146 whichbecame Patent 1292399 Jan. 19, 1919, and relates more particularly tothe filter for the water obtained by condensation of the steam utilizedin driving the turbine described in the said application.

In the accompanying drawings forming part of this specification, inwhich like numbers of reference denote like parts wherever they occur,

Figure 1 is a top plan view;

Figure 2 is a vertical longitudinal sec tional view;

Figure 3 is a side elevation of a locomotive showing the filter in situ;and

Figure 4 is a rear elevation for the same purpose.

The exhaust from the turbine 1 that forms the characteristic feature ofthe said patent, .is into the steam condenser and water-cooler 2 shownin Figures 3 and 4. The saidexhaust passes through pipes (not shown)into the said condenser 2. The condenser 2 is formed of a plurality ofsquare pipes 3, arranged as shown in Figures 3 and 4, which, by reasonof their form and arrangement, and particularly because of theserpentine course that the steam is obliged to pursue therethrough (asindicated by the arrows in Figure 3) cause condensation of the steam andits cooling because of the large area of pipe through which it passesbefore it reaches the exit, This exit is into pipe 4 that leads to thefilter 5 (shown in detail in Figure 2). The condensing effect of thesaid large area of pipe is augmented by the draft that flows among thepipes .3 when the locomotive is in motion, which draft is enhanced bythe hood fi that encloses the said pipes 3, except at their ends.

The water product of the condensation of steam in the condenser 2 ispurified in filter through the filter, entering through pipe 4 intochamber 11; thence passing through opening 9 into chamber 12; and thencepass- 1ng through opening 10 into chamber 13. From chamber 13 the waterpasses out of the filter through pipe 14.

In compartment 11 is contained crushed copper glance. In compartment 12charcoal is contained. Compartment 13 contains crushed lime-rock. V

Thus the water entering through'pipe 4 leading from condenser 2 flows 1na serpentine course, as indicated by the arrows in Figure 2, first,through the crushed copper glance of compartment 11, then throughopening 9 into compartment 12, and by the action of gravity travelsdownward through the charcoal compartment 12; thence it passes throughopening 10 into compartment 13 where it rises throughthe crushedlimerock and flowing outward through the pipe 14 to the water reservoir15, from which it is pumped by pump 16 as distilled water to the boiler(not shown).

It has been found that the use of copper glance, otherwise known ascuprous sulphide, operatesto prevent the fine particles of oil andorganic matter that might be present in the water as it comes from thecondenser or source of supply from passing through the charcoal and limerock.- When the water passes through the copper glance, the copperglance thereby becomes hydrolyzed and the hydrolyzed copper so formedserves to separate the oil and organic matter from the water and thusprevents these substances from passing to the compartments containingthe charcoal and lime rock. Itwill thus be seen that there is provided afilter that will take care of the very fine particles in suspension inthe water and which would pass through the charcoal or the lime rockinto the boiler causing corrosion and incrustation. F

This filtering of water does away with any sediment or residue such asis commonly found in b ilers and does away with cleaning orblowing outofboiler tubes which is% mentioned chamber being crushed copper a greatadvantage over types of boilers heretofore known.

It will be understood that both condenser 2 and Water reservoir 15 maybe located at any suitable place on the loco-motive, and may be borne orsupported thereby in any suitable manner.

Having thus described this inve tion, I hereby reserve the benefit ofall ch nges-in form, arrangement order, or use of parts, as it isevident that many minor changes may be made therein without, departingfrom the spirit of this invention or the scope of the following claims.

I claim- 1. A filter having three vertically dispose chambers, an inlet'at one end of the first chamber and an outlet at its other end and intothe second and an exit from the second at the opposite end from. itsinlet, theisaid exit forming an inlet into the third cham-' her, anoutlet from the last mentioned cham her at the end thereof opposite itsinlet and in alinement with the central longitudinal axis thereof, thefilter material in the first glance, in the second chamber charcoal, andin the third chamber crushedlimerock.

2. Av filter divided into three vertically dis- ;posed chambers andhaving an inlet pipe at its beginning and an outlet pipe at the topandin alignment with the central longitudinal axis of the third chamber atits outlet, there being, a communicating opening at or near the top ofand between the first two chambers and another communicating opening ator near the bottom of and between the second and thirdchambers.

3. A filter having three chambers in communication with each other sothat the liquid passed throu h the filter will traverse each of saidcham rs, filtering material in said chambers, the first chambercontaining crushed copper glance; the second or intermediate chambercontaining charcoal, and the third and last chamber containing crushedlimerock.

In testimony whereof I hereunto afix my I signature.
